Read and compare values from csv

Hi guys!
I have to transform one field of an input DataRecord only if another field in the same DataRecord is equal to a specific value read from csv file.

The transformation have to compare "UserCountryName" input field with a value read in the csv and if there is a match, it has to write the "UserCountryGeocode" output field with the respective value read in the file.
For example:

The metadata record input have this form:

ID | UserName | Sex | Text | UserCountryName | UserCountryGeocode | Opinion | EventImpact

The csv file have this form:

UserCountryName, UserCountryGeocode
Italy, 41.87 12.56

I used a Reformat component with a Java class, this is the code:

import com.opensys.cloveretl.ctl.CTLUtils;
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import org.jetel.exception.ComponentNotReadyException;
import org.jetel.exception.TransformException;

public final class CSVReader extends org.jetel.component.CTLRecordTransform{

	private String csvFile = "...."; //Path of file
        private BufferedReader br = null;
        private String line = "";
        private String cvsSplitBy = ",";
              
		@Override
		public void globalScopeInit() throws ComponentNotReadyException {
			
		}        

		@Override
		protected int transformDelegate() throws ComponentNotReadyException, 
				TransformException {
			
			
			String metadataFieldNames[] = getInputRecord(0).getMetadata().getFieldNamesArray();
			int metaFieldNames_Lenght = metadataFieldNames.length;	
			boolean StopScanCSV=false;
			int i=0;
			
			
			while (i<metaFieldNames_Lenght){
				
				
				if (metadataFieldNames[i]=="UserCountryName"){
					
					try{
						
						FileReader r=new FileReader(csvFile);
						br = new BufferedReader (r);
						while (((line = br.readLine())!=null)&&!(StopScanCSV){
							String lineCSV[] = line.split(cvsSplitBy);
		
							if(lineCSV[0] == CTLUtils.toString(getInputRecord(0).getField("UserCountryName").getValue())){
								getOutputRecord(0).getField("UserCountryName").setValue(lineCSV[0]);
								getOutputRecord(0).getField("UserCountryGeocode").setValue(lineCSV[1]);
								StopScanCSV=true;
							}
						}
						
						
						//No-match
						if !(StopScanCSV){
							getOutputRecord(0).getField(metadataFieldNames[i]).setValue(getInputRecord(0).getField(metadataFieldNames[i]).getValue());
							getOutputRecord(0).getField(metadataFieldNames[i+1]).setValue(getInputRecord(0).getField(metadataFieldNames[i+1]).getValue());
							
						}
							
						i+=2;
						
			        } catch (IOException e) {
			            e.printStackTrace();
			        } finally {
			            if (br != null) {
			                try {
			                    br.close();
			                } catch (IOException e) {
			                    e.printStackTrace();
			         }}}}
			         
	getOutputRecord(0).getField(metadataFieldNames[i]).setValue(getInputRecord(0).getField(metadataFieldNames[i]).getValue());
				i+=1;
			}
					
			return 0;
	
			}


}

I'd try to write only the String lineCSV[] to the output port and it works fine (the problem isn't the csv). But the entire code doesn't work correctly.
Other values (ID, UserName, Text and UserCountryName, Opinion, EventImpact) are write correctly but UserCountryGeocode not (i read always null values).
There is anyone can help me please?
Thank you!

Ps. Sorry for mistake in my english! I'm not so well.
